Constroma is the workspace where contractors and owners turn schedule data into rigorous Time Impact Analyses, fragnets, and EOT claims — in days, not months.
Trusted by contractors and consultants worldwide
No incumbent does both. P6 and Asta author but can't analyse delay. SmartPM and Nodes & Links analyse but can't author. Constroma owns the full lifecycle.
A modern CPM scheduling tool that reads, computes, and builds construction schedules with the rigour planners trust from P6 — without the weight, the licensing, or the dated interface.
A forensic delay-analysis suite that turns those schedules into defensible, methodology-grounded narratives — aligned to AACE 29R-03, the SCL Protocol, and FIDIC.
Open, render and explore any P6 schedule — Gantt, WBS, logic, calendars, float — in your browser, on any device.
FreeSee exactly what changed between two updates — added, removed, and the logic that was quietly re-wired.
FreeRecompute any schedule from scratch — forward/backward pass, float, critical path — matching P6 exactly.
FreeMap the bill of quantities and a coded resource dictionary to activities for cost- and resource-loaded curves.
Low-tierFull DCMA 14-point assessment with guided, reversible fixes — a baseline that survives a claim.
PaidIAP, TIA, Windows, As-Planned vs As-Built, Collapsed As-Built — with an AI layer that drafts the narrative.
PremiumEvery analysis is reproducible and auditable — aligned to AACE 29R-03, the SCL Delay & Disruption Protocol, and FIDIC.
Read, compare and recompute schedules for free, forever. Pay only for the baseline and forensic work that wins the claim.
